If you’re reading this on your trusty Sony Vaio, better turn it over and look for the fine print. Then go to this Sony site, to find out if yours is one of 440,000 Vaios being recalled because of faulty wires and overheating problems. Nineteen models in the TZ series (made in 2007-2008) are potentially problematic. Apparently, wires were improperly placed, were wearing, then short circuiting, then overheating. Sony, which announced the recall Thursday, said it has gotten more than 200 reports of overheating, including seven people who were burned, according to the Associated Press. About 72,800 of those laptops are in the U.S., Reuters said. If your product code and serial number pops up on the Sony site as one of the troubled Vaios, Sony promises to come to you for on-site repair at your house or office (or you can send it to a service center). Sony, you may recall, was also the maker of defective batteries that forced the recall of many thousand notebooks (from Dell, Apple, Hitachi and others) in 2006.

Is there anything more fun than trying to wake up a teenager at the beginning of the school year? A teenager who has spent the last three months sleeping until noon? The only thing that is likely more fun is watching what happens when Clocky the alarm clock goes off. Clocky is cute and has big wheels (pictured), and after your teen hits the snooze button once, Clocky rolls off the bedside table and rolls around the room, continuing to buzz loudly: under the bed, against the door, in the bathroom, until said teen has to get out of bed to find him. Beautiful! He’s $50 at Bed, Bath and Beyond. Another fun one is the flying alarm clock. It has a cute little propeller on its top, and when it goes off, the propeller spins and flies away, carrying the key that makes the alarm clock stop its incredibly loud screeching. Fabulous, and $11.48 at Amazon. It would probably be entertaining to watch the teen in bed when the Sonic Boom alarm clock goes off. It purports to be painfully, horrifically loud, with wildly flashing lights, and it comes with a little thingie you put under their pillow that vibrates wildly as the alarm goes off. It even says it’s only suitable for those 14 and older. It’s $55.78 (pictured). We found a few other interesting but less sadistic alarm clocks. if you’re a kinder, gentler parent. The Neverlate Executive clock has up to 21 different alarm settings over the course of a week, including “his and hers” alarms. Get it for $60 from ThinkGeek. Chumby is very cute and a bit expensive ($180) but it will connect wirelessly with the internet and wake them with any kind of video/audio widget you choose: news on CNN, a Lil Wayne music video, The Daily Show, or even a download of their mother screaming Get Up! Get Up!  The Matrix Cube is a clock for geeky sorts, consisting of three cubes that show the hour, minute and second. Stack the cubes in whatever way you like. Also from ThinkGeek, the Matrix is $35. This one is so silly we had to toss it in. The Hotel Phone alarm clock looks like an old-fashioned black corded phone. Set the alarm and the phone ($137) rings and a voice similar to one at a hotel will politely say, “This is your wake-up call.” This must appeal to people who never travel, as hotel wake-up calls are usually as unpleasant as, well, a teenager in the morning.

All TV stations will broadcast only in digital starting Feb. 17, 2009. If you’re reading this, you probably don’t need an analog-to-digital converter box for your TV, but your parents or grandparents or elderly friends who still rely on rabbit ears or rooftop antennas do. And they may not even know it (a January report said 36 percent of all Americans - predominately Hispanics - didn’t know about this impending change). Another report earlier this year said there are a little more than 14 million households - 13 percent of all households with TVs - that will lose their signals if they don’t buy the boxes (which cost from $40 to $70). The government’s TV converter box coupon program Web site answers most all questions, but that doesn’t help if the person doesn’t have a computer. You can help them apply for two free coupons worth $40 each at the Web site, or they can call (888) 388-2009. or mail an application to P.O. Box 2000, Portland, Ore. 97208-2000 (download the application here.) The coupons must come from the government, not retailers. The coupons (which look like plastic gift cards) expire 90 days after they’re mailed. Don’t assume all retailers will accept the $40 cards, so check first. More information is available from the Federal Trade Commission. Some words of caution: retailers are not allowed to charge tax on the government-funded portion of the boxes (the $40 coupon). Also, do not toss the antennas: They can still augment the signal. A Washington Post story several months ago warns of the “digital cliff” - digital signals are more easily interrupted and lost because of hills, trees and weather. The government site lists all the retailers (big box, online and telephone) who sell the boxes, but we found some discrepancies. A visit to BestBuy.com offers information, but they don’t sell the boxes online: you have to go to a store. This page shows you the three kinds they sell, at $60 each. Sears.com has a box on their Web site about the change, but clicking it takes you to the FCC site, and it appears Sears doesn’t sell the boxes (despite the government site saying they do). Target.com has one type that must be purchased in stores for $50.

There’s a lot of grumbling out there about the Apple 3G iPhone that came out in July. It seems that calls are dropping, like rocks. They’re blaming it on a German-made chip in the phone, and Apple is promising a software fix will be on iTunes soon. On top of the irritation at lost connectivity, Apple has sold so many of them, they’re not so special any more. Everybody seems to have one. So now how do you elevate yourself above the masses? Pop a fascinating case or cover over it, of course. You can go the basic route with leather or silicone skins,  or get one in a snazzy color for $25. Since you were aiming for a high tech look, the Invisible Shield by Zagg ($25) is made of a thin polyurethane film created by the military for helicopter blades. Cases.com has lots to choose from, including a snappy red leather crocodile cover for $127 (pictured). Not content to wear your iPod on your arm, now you can slap your iPhone on as well, with a $30 sport armband from Belkin (or their Spiderman-ish micro-grip, which is coming soon). A Web site called iPhone3Gcases.net certainly has to have a lot to pick from, such as the colorful Golla Calla fabric cover for $20. Get snazzier with the iWood by Miniot, carved from a single piece of wood and monogrammed with your logo or a personal message, for about $125. And if you really want to flaunt your phone, get the monogrammed Louis Vuitton leather holder for $320 (but check back because they’re out of them online right now - we guess everybody wants one, just like you).

Has a weekend of watching amazing athletes inspired you to leap off the couch and get into shape? Don’t be hasty. Gather some gadgets to get started with, or just to make you look cool in the trials. Impressed by the way the Olympic gymnasts fling their bodies around the pommel horse? Your variation on the rings competition could be the Perfect Pushup ($99), with rotating handles and adjustable swing arms to give you the feel for holding your body suspended in mid-air. Uhmm, yea. Ready to run? Don’t leave without a Sportline HydraCoach “intelligent” water bottle (pictured) that tracks your hydration level based on your weight, exercise level and your personal hydration goal.” It even factors in heat and altitude, for $27.95. You want to wear earphones while you sprint, but when in unfamiliar territory (like a running path), ambient awareness earphones ($80) will let you jog along with Lil Wayne and still hear sounds around you, such as screeching brakes and screaming. Now you’re starting to get serious, and this is a seriously odd device: a “core body temperature monitoring system” that consists of a data recorder you wear, which gets its information from a pill-shaped sensor that you swallow. We can’t find a price, but you may want to discuss that one with others before purchasing, anyway.  You’ll want a new scale to measure your progress, and a Tanita Inner-Scan scale will track not only your weight but body fat and body water percentage, muscle mass, physique rating, amount of visceral fat and, well, enough said. It’s $110. Is all this talk of exercise too exhausting? Then you probably just need to strengthen your remote-control muscles with an Xtensor hand exerciser ($40 from ThinkGeek).  It’s made for video gamers, but you wouldn’t want to get a thumb cramp and miss the synchronized swimming.

Oh, what a tangled web we weave … with all of our tech gear and corresponding chargers. Get a handle on all those cords and manage your family’s cell phones, MP3 players and digital cameras with a handy charging station. Pottery Barn’s lacquer Smart Photo caddy and recharger has a back cubby for portable electronics and a six-socket power strip concealed behind. Cubbies in the front stow desk accessories and three photo openings create a desktop gallery ($99). Plug and play your iPod while charging other electronics all in one spot. The lacquer Smart all-in-one (pictured) includes built-in speakers and a six-socket power strip ($169). Kids these days often have more gadgets than their parents, which means they could probably fill their own charging station. The kids docking station comes in a rainbow of colors and features cutouts like hearts and stars ($79). Bed Bath and Beyond sells a more basic model. The black 600 Denier charging station provides a home for up to four devices ($15; power strip sold separately). Brookstone’s mini charging valet is the perfect addition to your workspace, whether it’s at the office or at home ($30).
